Editor’s tips: Have we managed to convince you to try out a blue hair colour? If so, it’s worth investing in a colour protect hair care duo, such as the TRESemmé Colour Revitalise Shampoo and Conditioner. They’ll help to maintain your hue’s vibrancy between dye jobs, while also leaving it feeling healthy and soft.
